Member Function Documentation

◆ clearDrawing()

void RDKit::MolDraw2DCairo::clearDrawing ( )

overridevirtual

clears the contents of the drawing

Reimplemented from RDKit::MolDraw2D.

◆ drawLine()

void RDKit::MolDraw2DCairo::drawLine	(	const Point2D &	cds1,
		const Point2D &	cds2,
		bool	rawCoords = `false`
	)

overridevirtual

draws a line from cds1 to cds2 using the current drawing style in atom coords. If rawCoords is passed as true, the coordinates are used as is, if not they are assumed to be in the molecule coordinate frame and converted with getDrawCoords into canvas coords.

Implements RDKit::MolDraw2D.

◆ drawPolygon()

void RDKit::MolDraw2DCairo::drawPolygon	(	const std::vector< Point2D > &	cds,
		bool	rawCoords = `false`
	)

overridevirtual

draw a polygon. Note that if fillPolys() returns false, it doesn't close the path. If you want it to in that case, you do it explicitly yourself. If rawCoords is passed as true, the coordinates are used as is, if not they are assumed to be in the molecule coordinate frame and converted with getDrawCoords into canvas coords.

Implements RDKit::MolDraw2D.

◆ drawWavyLine()
